Abstract (en)

A vacuum gripper device comprises a two-part hollow disc-shaped housing 1 comprising a cap 2 and a closure plate 3, a multi-ejector vacuum pump 6 disposed in the housing 1, an air distribution manifold 7 attached to the cap 2, the manifold 7 having a compressed air inlet 9 which connects with an inlet port 10 of the pump 6, an exhaust outlet 11 which connects with an exhaust port 12 of the pump 6 and a vacuum connecting pipe 14 connected to the vacuum port 13 of the pump 6 and to the interior of the housing 1, the closure plate 3 being provided with a sealing skirt or rim 5 and a filtered aperture 16 to the interior of the housing 1, the exhaust outlet 11 being provided with a poppet valve 19 which opens and closes the exhaust outlet whereby when a compressed air supply is connected to the compressed air inlet 9, when the poppet valve 19 is closed air is caused to be emitted from the aperture 16 to clear contamination and help position the gripper device, and when the poppet valve is open a vacuum is formed on the underside of the closure plate to cause the gripper device to grip an adjacent surface (Fig.3). <IMAGE>
